TECHNICAL FIELD

The present invention relates generally to systems, methods and apparatus for the dispensing of material. Embodiments of the present invention provide dispensers, and particularly automatic dispensers, and even more particularly, automatic touchless dispensers for dispensing material (e.g. edible material) to a user. The present invention is also directed to retrofitting existing hand operated dispensers (e.g. EZ-PRO™ line by Rosseto) so as to convert to these dispensers to automatic, touchless dispensing of material without significantly changing the components, operation, etc. of the dispenser.

BACKGROUND

It is known in the art to dispense materials using mechanically operated dispensers. Such dispensers can be found in hotels, motels, restaurants and business. These devices use either paddles, balls or an impeller which, upon rotation, moves an amount of material or product (e.g. food such as, for example, cereal) from a material or product storage area to a dispensing chute or container. Upon approaching the device, a user simply places a dish or bowl under the chute and turns an element, such as a handle, attached to the paddles, ball or impeller. A portion of the product then falls into the dish. If the user wants more product, the handle is turned again.

Existing dispensers have a number of shortcomings. In particular, these traditional dispensers require a user to press, pull, or rotate an element (e.g. a lever, knob, etc.) on the dispenser in order to actuate the dispensing function, which contact can generally be unsanitary and possibly spread pathogens. In high user traffic areas where food and other edible items are dispensed under user control, such as, for example, snack rooms or retail displays in commercial establishments (such as, for example offices, grocery stores, retail stores, bulk food stores, etc.), users may not wish to touch or pull a lever that others have touched. In the health care arena, such contact can be even more concerning and unhygienic, raising health and contamination concerns. Dispensers designed for use in public or semi public venues or areas (as opposed to domestic use) may be particularly susceptible to such concerns.

One solution to the contact/hygiene problem presented by users pushing or pulling portions of the dispenser in order to dispense material has been to design dispensers that automatically (e.g. not requiring a user to actuate a component) dispense a desired amount of material, so-called touch-free or touchless dispensers. This prevents the user from coming into contact with any part of the dispenser, and is particularly beneficial where the transmission of bacteria and viruses are of particular concern. However, current designs of dispensers also present some challenges and problems.

For example, some automatic dispensers fail to provide a consistent and accurate amount of material upon each dispensing cycle. It is thus accordingly desirable to have a reliable, consistent dispenser design that will automatically dispense a desired amount of material per use.

Another problem arises with existing non-touchless dispensers. It may be difficult and costly to replace or retrofit these dispensers with touchless options. If a business owner, operator, user, etc. wishes to change from a non-touchless automatic dispenser to an automatic touchless dispenser, a new dispenser could need to be purchased causing excess cost and inconvenience.

There remains a need for automatic touchless dispensers that can be used in dispensing material in an accurate and hygienic manner.

SUMMARY

Accordingly, it is an aspect of this invention to overcome some of the disadvantages of the prior art.

It is desirable to provide an automatic touchless dispenser that can be used with pre-existing dispensers. It is also desirable to provide a dispenser that can be easily opened and secured for replacement of the material reservoir contained inside the dispenser.

Out of the page towards the reader is in the positive z direction. Into the page or away from the reader is in the negative z direction. The force of gravity typically acts parallel to the y-axis, unless context indicates otherwise.

Preferred embodiments of the present invention can be implemented in numerous configurations depending on implementation choices based upon the principles described herein. Various specific aspects are disclosed, which are illustrative embodiments not to be construed as limiting the scope of the disclosure. Although the present specification describes components and functions implemented in the embodiments with reference to standards and protocols known to a person skilled in the art, the present disclosures as well as the embodiments of the present invention are not limited to any specific standard or protocol.

The present invention relates to systems, methods and apparatus for automatically and touchlessly dispensing an accurate predetermined amount of a product. In a preferred embodiment of the present invention, the products are food or other snack type of products, such as, for example, ice cream toppings such as sprinkles, crushed and chopped nuts, chocolate flakes, candy, crushed seeds, bulk spices, sugar, breakfast cereal, whole nuts, dried fruit and the like.

An aspect of the present invention is directed to a system for retrofitting existing hand operated food dispensers (e.g. EZ-PRO™ line by Rosseto) so as to convert these dispensers to “touchless” dispensing. This system requires only minor modification of the existing dispenser. It does not fundamentally change the way the dispenser operates with respect to parts that touch the food product so it should not impact any food service certification of the dispenser. FIG. 1 shows an embodiment of the present invention that uses a typical dispensing apparatus or dispenser 100 to dispense products. As shown in FIG. 1 , dispenser 100 is generally provided with a manual operated rotating handle connected to a shaft that controls the dispensing of the product or material contained in the dispenser. As shown in FIG. 1 , there is provided a container disposed within the dispenser, the container adapted to hold the material to be dispensed. A handle/shaft subassembly 100 a is disposed with a product canister or container 100 b. Container 100 b has a top opening and a bottom opening to allow for material or product to be added to the container and released from the container through the operation of the handle/shaft subassembly 100 a. In operation, the dispenser would typically dispense product or material to a user when the user manually rotates the handle, which turns the shaft to release the material to the user. Typically, some form or system of rotatable, dispenser ball, paddle or other shape (e.g. an auger type dispensing system, not shown), usually with a hard smooth surface, is disposed with the canister 100 b and can be rotated by the rotatable handle and shaft mechanism, which typically passes through the dispenser ball, paddle or other shape. The dispensing ball or other rotatable part fits into the container and is turned by handle/shaft mechanism 100 a when the handle is manually rotated or turned such that the ball rotates within the canister 100 b. The rotatable part has been called a ball for convenience; however, it does not necessarily have to be spherical or have a ball configuration. In fact, it can be any shape as long as it can rotate within the canister 100 b. The handle/shaft subassembly 100 a passes through the ball so that when 100 a is rotated, the ball also rotates. A person skilled in the art will understand that any method of causing the ball or paddle to rotate through a shaft is within the scope of the present invention.

A person skilled in the art will understand that the rotatable ball, paddle or auger may have a cavity or opening that can be sized to dispense a precise amount of material or product. The cavity can be any shape or depth; however, it is preferred that it have a smooth surface and contour so that the product slides out of or through it when it becomes aligned with dispensing opening of the container 100 b. The present invention allows the use of many different size balls or rotatable members with many different sized cavities and/or openings. Any size or shape of rotatable member and any size or shape of cavity is within the scope of the present invention. In one example, the cavity may face upward into the product and typically fills with product. As the handle/shaft subassembly is then rotated, the ball or paddle rotates to delivers the contents of the cavity through the opening or container 100 b where it is dispensed.

The dispensing apparatus/dispenser 100 can be attached to a stand assembly 110. Stand assembly 110 may provide a generally horizontal serving portion 110 a where dishes or other items (not shown) may be placed to receive the material being dispensed and a generally vertical back cover 110 b having a canister mounting plate portion 110 c. The vertical back cover 110 b supports the container 100 a provided with the dispenser 100 and attaches thereto via canister mounting plate portion 110 c. The back cover portion 110 b also serves as a point of attachment for the components of the automated rotational dispensing apparatus 120. An example of dispenser that may be used in association with the present invention is a line of hand operated dispensers and stand assemblies sold under or in association with the trademark EZ-PRO™ by Rosseto. While this current implementation is targeted for the EZ-PRO™ line of dispensers, the features and design approaches described here not intended to be limited to this type of dispensers. The concepts described are applicable to a wider range of dispenser designs that employ a rotational dispensing mechanism. A person skilled in the art will understand that a number of other dispenser and stand assemblies could be used in association with the present invention, including, but not limited to, the dispensers sold under the following company and/or brands CAL-MIL™, ECOBOX™, ZEVRO™, COFRIMELL™, TABLECRAFT™, TOOTSI IMPEX™.

FIG. 1 shows the components of an embodiment of the present invention, namely an automated rotational dispensing apparatus 120 that may be used in association with the dispenser 100 and stand assembly 110. As shown in FIG. 1 , there are provided three dispensing apparatus 120 attached to one vertical back cover portion 110 b. A person skilled in the art will understand that other configurations of dispensing apparatuses and covers are encompassed within the invention and may be selected based on the needs of the user. For ease of reference, only one of the dispensing apparatuses will be described, but a person skilled in the art would understand that each apparatus 120 has the same configuration.

In FIGS. 1 to 3 , there is provided a motor subassembly or rotary actuator 125 attached directly or indirectly to the back cover 110 b. Embodiments of the present invention are directed to systems, methods and apparatus that transfer or transmit torque from the motor subassembly through a coupler or coupling system into the handle/shaft subassembly 100 a in dispenser 100. This coupling design allows efficient torque transmission, easy, tool-less removal of the dispenser-side coupling for servicing and easy, tool-less installation and removal of the canister for servicing (e.g. adding food to the dispenser, washing the dispenser, etc.). In a preferred embodiment, as shown in FIG. 2 , the motor subassembly 125 further comprises a motor engagement or coupling device 125 a which is rotated through engagement with motor (not shown) disposed in 125 (see also FIG. 4 ). As shown in FIG. 3 , a preferred embodiment of the present invention illustrates the first and second couplers, 125 a and 125 c respectively, engaged with one another in their operating position. Motor coupling device 125 a is designed to engage with both the motor and the container engagement or couple device 125 c (see FIG. 3 ). The motor (not shown) disposed in 125 engages with device 125 a in order to transfer or transmit the torque produced by the motor to the handle/shaft subassembly 100 a (See FIGS. 5A and 5B). FIG. 4 shows the motor-side first coupler 125 a. As shown in FIG. 4 , there are provided a plurality of recessed channels 126 designed to functionally engage with the ridges or ribs 140 (see FIG. 5A) of the dispenser-side second coupler 125 c. In a preferred embodiment, it is this interface between the first and second coupler that provides the torque transfer mechanism.

FIG. 2 also provides a ring housing subassembly 130. Ring subassembly 130 is attached directly or indirectly to the subassembly 125. In a preferred embodiment, ring subassembly 130 provides a generally circular portion 130 a (see also FIG. 2 ) with clearance for dispenser 100. Canister 100 b can fixedly or unfixedly mounted to or resting on the ring housing subassembly 130 a so as to allow to the handle/shaft subassembly 100 a to be engaged with the motor subassembly 125 so that when motor subassembly is activated the handle/shaft subassembly 100 a rotates thus releasing material from the container 100 into dishes or other items (not shown) that may be placed to receive the material being dispensed. Ring housing subassembly 130 is also provide with a sensor 130 b (see FIG. 1 ) to detect motion so as to trigger the activation of the motor. Sensor 130 b can be any form of suitable sensor such as, for example, but not limited to, motion, heat, distance and the like. It will be understood by a person skilled in the art that sensor 130 b is operatively connect to the motor so that when the appropriate level of motion is detected by the motion sensor 130 b, the motor is activated. As a result, motor coupling device 125 a is rotated, which rotation motion is then transferred to container engagement or couple device 125 c, which rotational motion is then transferred to the handle/shaft subassembly 100 a. As a result, material is then dispensed. It will be understood that the timing, speed and power of the motor may be set by the user and concurrently or alternatively may be under the control of a network ready device and further subject to software or hardware controls

FIGS. 1 to 4 illustrates the container engagement or couple device 125 c which is shown in greater detail in FIGS. 5A to 5C. As shown in FIGS. 5A to 5C, container engagement or coupling device 125 c is shown with a plurality of ridges or ribs 140 protruding that are designed to sit in and engage the channels 126 in the motor-side first coupler 125 a for torque transfer (shown in FIG. 4 ). Additionally, in a preferred embodiment, there is provided within coupler 125 c a centrally disposed split 135 that interfaces with shaft of the handle/shaft subassembly as shown in FIG. 5B. In a preferred embodiment, container engagement or couple device 125 c (see FIG. 5C) is provided with a shaft engagement portion 135 for operatively engaging the handle/shalt subassembly. As shown in FIG. 6 , the handle/shaft subassembly can be designed with a generally D shaped end portion 132 of the shaft 131 that is designed to engage with the convergence or termination portion of slit 135; there is also provided a groove portion 136 upstream of the D-neck. As shown in FIG. 5C, coupling device 125 c also has a plurality of ridges 140 adapted to operatively engage with motor engagement or coupling device 125 a. The split side of 125 c features a geometry that self-aligns the D-neck 131 downstream from the handle along the dispenser rotating shaft of handle/shaft subassembly 100 a. As shown in FIGS. 5A and 5B, there is provided the groove 136 disposed to releasably engage within the slit side 135 that engages with the upstream portion of the dispenser rotating shaft, the groove shaped to engage the D-neck end portion 131 so as to transmit torque from the rotating second coupler to the rotating shaft. As can be seen in FIGS. 5A and 5B, the D-neck end portion 131 also has a detent feature that snaps the second coupling 125 c into position onto the neck for ease of installation. A person skilled in the relevant art would understand that any configuration for engagement with the differing components of the present invention that allows for the transfer of the rotational movement would be encompassed by the present invention.

In a preferred embodiment, the slit side of the dispenser side second coupling 125 c is a serviceability feature in that it allows the user to quickly remove and re-install the coupler on existing dispensers. This capability allows for ease of reassembly/disassembly of the dispenser during initial assembly and for regular cleaning. The detent retention feature is also useful in that it keeps the dispenser side coupling from coming off the shaft while servicing the dispenser.

The design of the torque transfer ridges or ribs 140 and the channels 126 enables a relative motion of the couplers in one direction. This aspect of the invention allows for the tool-less removal and installation of the invention to the dispenser canisters.

As shown in FIGS. 7A to 7D, a preferred embodiment of the present invention provides for mounting/dismounting of the dispenser assembly 100. In a preferred aspect of the present invention, there is provided the ability to have motion of the canister 100 b within the dispenser assembly 100 relative to the canister mounting plate 110 c. Defining engaging with or removal from the canister mounting plate 110 c as along the y-axis (or in the Y direction (+ less engagement and − more engagement)) and closer to and or away from the vertical back cover 110 b as along the x-axis (or in the X direction (+ further apart and − is closer)), the canister 110 b may be first rotated in a small clockwise direction to position the dispensing chute through the sensor ring. The canister may be moved in a diagonal direction (−X direction and −Y direction) to attach the canister to vertical back cover to engage with the canister mounting plate portion 110 c. This relative motion requires a coupling subassembly (e.g. 125 a and 125 c as shown in FIG. 3 ) that is capable of a relative motion along the y-axis (e.g. in the Y direction) while being installed. The two channels 126 (as shown in FIG. 4 , for example) and ribs 140 allow for this when they are oriented to line up along the y-axis.

As shown in FIG. 8 , the embodiments of the present invention may uses an IR based, ultrasonic or laser based distance sensor 130 b that is capable of reliably measuring roughly 20 mm up to 250 mm in front of the distance sensor. Preferred examples of IR based distance sensor include SHARP GP2Y0A41SK0F; alternatively, other forms of distance measurement solutions are also possible including ultrasonic distance measurement devices such as OSEPP Electronics HC-SR04. It may also employ a single LED light strip (not shown) to inform the user of its current state to provide user feedback on the use of the dispenser. The light strip is aimed inward and away from the user to minimize glare and rely on the reflected light for illumination. The controller manages the LED's light output to indicate current operating mode and aid the user in the use of the touchless dispenser. The distance sensor 130 b is positioned to monitor the area in front of the dispenser roughly where the manual knob is located. This area serves as the interface zone with the user. See FIG. 8 for an illustration of the measurement location. The sensor will sense the presence of a target (user's hand, for example) and the controller will react based on programming. In a preferred embodiment, FIG. 8 shows a preferred measurement or interface zone of between approximately 20 mm to 250 mm for the detection range. The preferred shape of the measurement zone 200 as shown in FIG. 8 is representative of the general shape of the measurement range of the present invention.

The state diagram in FIG. 9 shows how the dispenser operates normally. The LED is used to indicate the different states that the dispenser is in. It is meant to let the user know that a target (their hand, for example) has been detected and inform when a delay/cooldown timer is active. Delay timers are employed to properly time actions of the controller. They are used to ignore spurious inputs and grants the user time to place their serving bowl under the dispenser and to retrieve their serving bowl after dispensing without inadvertently activating the dispenser. The dispenser will monitor all the sensors but once a valid target is detected, it will ignore all the other sensors.

Informing the user of the amount they have received based on weight and nutritional value is highly desirable for bulk dispensing. This provides the user the same information they would find in individually packaged products. This can be accomplished by determining the weight of the dispensed product and using the information in the nutrition panel of the product to generate nutritional information. There are two methods envisioned for determining the weight of the dispensed product: (a) Measurement based on dispensing time and speed; or (b) measurement based on dispensed weight.

In a preferred embodiment, there may be provided a system for determining the amount of material or product dispersed by determining dispensing time and speed. The computer as used in the present invention has access to the dispensing time (e.g. how long the motor subassembly is rotating) and dispensing speed (e.g. how fast the motor subassembly is rotating). Using data tables achieved by standardized testing in the computer which were generated from experiments to measure dispensed weight based on dispensing time and speed of different products, the computer can provide an estimated amount of dispensed product via a small computer display on the dispenser after the product has been dispensed.

In a preferred embodiment, there may also be provided a weight sensor. By adding a weight measurement sensor (loadcell, etc.) that can measure the weight of the product in the canisters, the computer will have access to the initial weight of products at the start of the dispensing cycle. The computer can measure how much weight has been dispensed and provide an estimated amount of dispensed product via a small computer display on the dispenser after the product has been dispensed.

In a preferred embodiment, the present invention can be networked such that it can be operated, monitored and serviced remotely. As such, a remote operator can monitor the amount of material dispensed, directly or indirectly control the dispensing of material. In addition, diagnostic functions may also be performed o the dispensing device of the present invention.

By making the computer aware of the estimated dispensed amount, additional user interaction features are possible. It is envisioned that a smartphone App can be developed that allows the user to input their desired amount of product based on nutritional value (calories, protein, etc.).

Using some touchless method (QR code, NFC), the user can use an application on a mobile device (e.g. an “App”) to interact with the dispenser computer which would dispense the amount desired by the user. The use of App may also allow for remote control of the device. For example, in a preferred embodiment, a networked dispenser of the present invention can indicate the device status to a user (e.g. that the dispenser is empty or nearly empty and requires refilling). This can result in more efficient servicing of the present invention.

The ability to control and provide this data to the user or the user's organization, many possibilities are opened up to encourage mindful snacking habits.
